PIC keeps resetting when executing subroutine

[mackrackit]

Just for fun, replace the tranistor driveres, buzzers, lamps with LEDs.
Could still be a hardware problem and this will tell.

I can remove the buzzer and lamps by unplugging a connector and the PIC still resets as I can see what's going on with the LCD screen. I tried a different computer and the result is the same.....

Maybe you are browning out due to inadequate power supply

I checked that also with my scope. Power is solid.

I am using a 2A DC/DC converter PT6212E-5 on my circuit board with plenty of bulk capacitance. I have used these parts on many of my other PIC projects without problems. I am using a 3S1P Lipoly battery pack that can supply 30A cont current for my 12V input until it can be installed. I am using PBP V2.46 with the patch installed and the latest beta programming software with my epic programmer. The epic software on CD V3.30 gives the same reset problem...

I know the following is commented out, but not sure what is going on here:

'ADCON0 = %11000001
'ADCON1 = %10001110

'trisa = %00001110
'trisb = %11110111

You want to make sure all the analog inputs (ADC and Comparators) are set to digital. Also I think your TRIS directives are backwards (i.e. desired output are inputs and viceversa). Again this is commented out, but you should be defining these things at the beginning.

Not sure what the real problem is, but somehow I think you are having a stack overflow.

Try replacing the "GOsub warning" with "GOto warning"; and "RETURN" with "GOto monitor".

Try the attached file removing the .txt

Also as languer noted, your TRIS set up is commended out. Why? According to your variables, there is a conflict with the TRIS settings. Perhaprs an input is not biased and seen as high or low irrelevant what you really do on the pin.

Hi Ioannis, I would also modify label light as per the attached code, because otherwise if portA.0 is zero then program will put high binlight and end.

light:
if PORTA.0 = 0 then
high binlight
else
alarm = 0 
endif
GOTO Monitor

end

Nice Al. I missed that!
